Abstract

A problem with unpaved roads is that the road is easily damaged when traveling thereon. The present application provides a surface mat for solving this problem comprising a first mat (1 a) and a second mat (1 b), each mat having a series of substantially parallel beams (2) and a plurality of spinal rods (3), the plurality of spinal rods (3) being substantially vertical and passing through the beams and connecting the beams to one another. Each mat also has an engagement member (7), the engagement member (7) being disposed adjacent an edge of the mat such that one of the spinal rods passes through the engagement member. The mat connects the first and second mats to each other by means of the connecting rod (8), the connecting rod (8) passing through and connecting the joint (8) of one mat to the joint (8) of the other mat.

Description

Pavement mat

Technical Field

The present application relates to a mat for providing a road surface.

Background

It is known to cover the ground with a mat (e.g. in unpaved areas) to provide a better surface for the vehicle to travel on, which would otherwise have to travel on, the bad ground. Ban Ting (banking) in US 2006/0222804 discloses a road mat in which a series of beams are arranged in parallel, each beam being located in a card grid of the fabric mat itself. However, the manner in which the Ban Ting mat is constructed is overly dependent on the fabric, which makes it susceptible to wear. It is an object of the application to provide a useful alternative at least in some way.

Definition of the definition

The term "comprising" or "having", if used in relation to one or more features, in each case means the smallest feature present, but does not exclude the option of there being other features not mentioned. The same applies to derivatives such as "include" and the like.

Detailed Description

Referring to fig. 1, a mat 1a has a series of beams 2 arranged in parallel. In this embodiment, the beams 2 are bonded in groups of two or four and are connected and tensioned by a series of spinal rods 3 extending vertically through the beams 2. As shown, the end of each spinal rod 3 is recessed into the end beam and secured therein by a lock nut 5. A handle 6 is provided in the side recess to provide a grip for carrying the mat when required.

Fig. 2 shows one of the beams 2a at the end of the mat in detail, and fig. 3 shows one of the beams 2b in detail in the central part of the mat. These beams allow the spinal rod 3 to pass through the holes 4 shown in phantom.

Fig. 4 shows how four mats 1a-d are connected "side-to-side" and "end-to-end". As shown, spinal rods 3 at adjacent corners of mats 1a, 1b are connected to each other by a locking plate 7 and a center connecting rod 8 of bolts 9 provided at both ends. The spinal rods 3 at the adjacent corners of the mats 1c, 1d are also connected to the connecting rods 8 in the same manner.

More specifically, referring to fig. 5, the locking plate 7 has one hole at each end. In each case, the associated spinal rod 3 passes through one of the holes and the central connecting rod 8 passes through the other hole. As also shown, the sides of the beams have spacers 10 between adjacent end beams 2a adjacent the locking plate 7. Fig. 6 shows one of the locking plates 7 in more detail.

As shown in fig. 7, the locking plate 7 is pivotable about the associated spinal rod 3 and the connecting rod 8. This means that there is some degree of "give-away" between the mats.

Referring to fig. 8, in use, the mats 1a-d are connected to one another as described above, e.g., such that they extend together from one side of the soil path to the other. Additional such mats are added in the same manner in front of and behind the sets 1a-d, extending over unpaved or otherwise unsuitable ground in a repeated manner, providing a running surface for the vehicle.

The mat spreads or dissipates the heavy load over one or more beams 2. This may protect the underlying ground from point loads that could otherwise cause rutting or other ground damage. Fig. 9 shows the force distribution of the wheel weight with (a) and without (B) pads. At a, the downward force is significantly more distributed at the surface than at B.

In addition, the mat provides improved wheel grip for the vehicle when the underlying surface is muddy.

Matting is particularly useful for providing temporary roads or other surfaces, but may also be used on permanent surfaces. It can be used to provide better vehicle access in a construction or civil engineering environment in areas that are remote or difficult to access, such as mining sites or where electrical wiring is being installed. The padding may also be used to provide a walking surface to prevent the work area where walking personnel enter from becoming muddy. By adding mats laterally and longitudinally as desired, one can lengthen or widen the road or other surface as desired. Damaged or worn portions may be easily repaired, such as by replacing beams or other components as needed.

Preferably, the beams are in each case hot pressed heavy bamboo outdoor panels, such as moso bamboo. Each mat is preferably about 2000 mm wide, 3000 mm long and 70 mm thick and has a compressed density of about 1050-1200 kg/cubic meter. However, other sizes and compressed densities may be used depending on the intended end use. In some embodiments of the mat, each beam 2 may be 140 mm wide, 2000 mm long and 70 mm thick. Preferably, each mat has three spinal rods 3, but the number used may depend on the overall size of the mat.

Although some preferred embodiments of the present application have been described by way of example, it should be understood that modifications and improvements may be made without departing from the scope of the following claims.

For the purposes of this disclosure, this document hereby discloses any combination of one or more of the items, features, or steps referred to herein, and any other items, features, or steps disclosed herein, in each case whether or not such combination is claimed.
